The Unity migration operation is not reversible. Make sure to back up your Unity project before you proceed.

If the Unity project is under source control, make sure to check out the whole Unity project folder before starting the migration. Otherwise, the migration will fail because it won't be able to modify the files successfully.

Before you install the Wwise integration, you need to make sure your Unity project is in a state where it can compile successfully without any errors. (Warnings are OK.)

This installation procedure assumes that you already have a Unity project containing a previous Wwise Integration package. For new installations, please refer to the Installing a Wwise Integration Package for the First Time page. Unlike other Unity plug-ins, you need to leave the previous Wwise Integration package installed in order to upgrade it to a newer version. The Launcher will install the new features and bug fixes, and then migrate the previous Wwise Integration to the newer version.

Warning: Do not delete the previous Wwise Integration before installing the new one as it will result in losing all the hard work you've done integrating Wwise audio in your game.

The upgrade is done in a 3-step process. First you need to update your Wwise project to the new version you wish to use and then you need to do the same with your Unity project.
